One Tin Soldier

Everybody remembers "One Tin Soldier" as the theme song from the movie "Billy Jack", but this was not its first incarnation. The song was originally recorded by the Canadian pop group "Original Caste", essentially a one-hit wonder group. "One Tin Soldier" was their only even slightly successful song, reaching as high as #34 on the top 40 singles list in 1969. The song was written for Original Caste by the successful production team of Dennis Lambert and Brian Potter, who wrote hit songs for a number of pop groups in the late 1960s and early 1970s.

One more interesting fact: the song is a blatant knockoff of Pachelbel's Canon, using exactly the same chord progression.
